Network secondary distribution system fault current analysis and application

Network secondary distribution systems are typically designed to ensure sufficient current is available to clear the most severe type of fault which is the solid fault. The procedure presented in this paper analyzes a network secondary distribution system for the expected performance of secondary cable circuits during solid type faults. By satisfying the criteria presented in this paper, it is expected that solid type faults will be cleared at the point of the original fault quickly and minimize any collateral damage.
